No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

An information disclosure vulnerability in OpenSignLabs OpenSign through 2.37.0 allows unauthenticated remote attackers to map any email address or username to its internal user objectId via the getUserId Parse cloud function. The function performs no authentication before resolving and returning the internal identifier. An attacker can use this to enumerate user accounts and target subsequent attacks.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
